ASUS Z77 Sabertooth And SSD

post #1 of 3
Thread Starter 
I currently have some weird Boot problems I assume it has to do with my setup and bios settings.

I have the SATA3 ports hooked up to my Raid 0 SSD drives that I use mainly for my games.
and then the next port (SATA2) is my other SSD 120GB that Use as my boot drive.

For some reason, more frequently than random, when I reboot I get hit with a "cant locate Boot MGR" message or blank screen with a blinking cursor.

I usually have to reboot, enter bios and manually Boot to my boot SSD.

I know that this is caused by my external drive and other USB connected devices, but how can I set it so no matter what the bios should only look for the OS in this one specific port. I dont understand why its doing this. I've looked almost everywhere in the bios to see if any other drive was put above the Boot drive in the priority list, but my Boot SSD is listed as first every where.

That is my first question/problem.

Second, running SSD SATA3 in SATA3 or SATA2, does it matter? the Sabertooth only has 2 SATA3 ports so I assumed putting my game drive on the fastest is going to decrease load times. but does it matter when we are talking SSDs ?


Also I'm not sure if I'm calling them the right interfaces...Sata 3 and Sata 6 (3Gbps & 6Gbps). excuse me.

In the BOOT section of the BIOS, disable everything you DON'T want to boot from.

As for ports, The various SATA busses don't "control" drive speeds. Though it can limit transfer rates.

The Buss speed (6/3/1.5) is the maximum data transfer rate the buss can handle. Putting a drive or an array on a buss that is slower than the drive can transfer data will limit transfer rates, but the converse, a slow drive in a fast bus, will not make the drive run faster.

An analogy:
Speed limits on a highway.
If a car will go 100 mph, but you drive it where the speed limit is 50 mph, the car will only be going 50 mph.
If a car can only go 50 mph, but you drive where the speed limit is 100 mph, the car will still only go 50 mph.

Hm, I set my Boot drive to the 1st spot and disabled all other slots (Priorities)

But now the boot is tremendously slow, it takes a good 40-60secs to reach the Raid screen ( a screen I see every time since I created my Raid 0 array, it just shows the Raid 0 and the other disks not in the array) then another 30-40secs to boot to Windows 7 homescreen.

Its never taken this long!

the usual boot time is like 5-15secs to home screen.


SSD:
I dont think I will go ahead with changing the Raid 0 SSD locations, just because I bought them for speed, 6, and putting them in the S3 slots would be just wasting my $$.
Now I just need to teach bios how to tell the difference between non-boot drive and the drive I want to boot off of.
